But because present industrial camera great majority are for focusing camera (focal length of camera lens is changeless in shooting process); Owing to can't adjust focal length; When taking the element of differing heights; Can't all elements be taken into identical sharpness, often the image of indivedual higher elements is fuzzy, also just can't detect the quality of higher elements.

Summary of the invention

The main task of the utility model is the defective that will overcome prior art; A kind of automatic optical detection device is provided; Height according to different elements; Automatically the height of regulating industrial camera is taken to change over as object distance, thereby improves the Equipment Inspection ability with the image that obtains identical sharpness, thereby improves the overall quality of SMT technology.

The technical scheme that the utility model adopted is:

A kind of automatic optical detection device; It is characterized in that: comprise pedestal, loading plate and object to be detected anchor clamps; On pedestal, be provided with first line slideway; Above first line slideway, be crossed with second line slideway; Loading plate is installed on first line slideway, and the object to be detected anchor clamps are installed on the loading plate, and said automatic optical detection device also comprises first driving mechanism, IMAQ mechanism, second driving mechanism; First driving mechanism is connected with loading plate and drives loading plate and moves before and after on first line slideway; IMAQ mechanism be installed on second line slideway and in the second drive mechanism lower edge the second line slideway move left and right, IMAQ mechanism comprises the 3rd driving mechanism that industrial camera, lighting source, driving industrial camera and lighting source vertically move up and down, wherein first driving mechanism, second driving mechanism, the 3rd driving mechanism, industrial camera and lighting source all are electrically connected with the corresponding port of the data handling system of automatic optical detection device.

Said first driving mechanism comprises first drive motor and first screw mandrel; The output shaft of first drive motor drives with first screw mandrel and is connected; First screw mandrel connects loading plate, and said second driving mechanism comprises second drive motor and second screw mandrel, and the output shaft of second drive motor drives with second screw mandrel and is connected; The second screw mandrel connection layout is as collecting mechanism; Said the 3rd driving mechanism comprises the 3rd drive motor and the 3rd screw mandrel, and the output shaft of the 3rd drive motor drives with the 3rd screw mandrel and is connected, and the 3rd screw mandrel connects industrial camera and lighting source respectively.

The coaxial industrial camera below that is installed in of said lighting source, lighting source comprises lampshade and is arranged on the lamp source on the lampshade inwall circumference that the corresponding industrial camera camera lens in lampshade top place is provided with open-work.

Said first drive motor, second drive motor, the 3rd drive motor are step motor or servo motor.

The beneficial effect of the utility model is:

The utility model is controlled the relative position of first driving mechanism, second driving mechanism adjusting IMAQ mechanism and determinand automatically through data handling system; Thereby reach the optimum condition of detection; Control the 3rd driving mechanism and regulate the distance of industrial camera and lighting source and object to be detected; Realize automatic focusing thereby reach, realize the accurate test of robotization to change object distance.

Compared with prior art, the utility model can satisfy the detection requirement of the testee of differing heights, can detect product quality more exactly; Wiring board and component mounter technology detect and is the front-end process that electronics is made, and is bad through the quality of stopping front-end process, can avoid subsequent technique repeat bad, thereby greatly reduce the cost of whole production flow process.
